No. 489,699 1 Claim. (Cl. 87-7) ABSTRACT OF THE DISCLOSURE A tubular rug, comprising a rope having a central core member and two side core members, one on each side of said central core member, a plurality of first covering yarns wound in one helical direction around the outside of the three side by side core members, and a plurality of second covering yarns wound in the opposite helical direction around only the central core member and interwoven with the plurality of first covering yarns, said rope being in side by side lengths which together make up the rug.

Conventional tubular rugs have been made up by winding covering yarn around the whole outer face of one or several core members, or by winding covering yarns on rope core members on both sides of an intermediate rope core member and winding the covering yarn alternately and in different helical directions on the intermediate common rope core member. Accordingly, the rope core members wrapped with the covering yarns can be arranged only in an ellptical form, so there exists, with a tubular rug formed from this type of covered core members, the lirnitation that a tubular rug having a rectangular shape cannot be made.

The object of the present invention is to provide an elegant and splendid tubular rug having a rectangular shape, and on which the covering yarns are wrapped very closely.

According to the present invention, the rope core made up into a tubular rug comprises at least side core members on both sides of the central core member. The desired numbers of first covering yarns, which have different colors, are wound helically around the outer side of these three core members, while other desired members of second covering yarns which have different colors, are wound in the opposite helical direction to the said first covering yarns only around the periphery of the central core member, and these second covering yarns are twisted between individual core members with the said first covering yarns which are wound, around the outer side of the three core members. Due to this twist, a covered rope having a central core member which projects convexly therefrom is obtained and a tubular rug can be formed from this rope by arranging this rope in an oval form or arranging several lengths in a row to produce a rectangular rug.

These facts and the object of the present invention Will be apparent from following specification and drawings, in which:

FIGURE 1 is a perspective view showing a portion of a tubular rug made of rope lengths according to the present invention.

FIGURE 2 is a schematic plan view of a rope adapted to be formed into a tubular rug, showing the manner of wrapping the covering yarns on the core members;

FIGURE 3 is a perspective view of the rope of FIG- URE 2; and

FIGURE 4 is a plan view of the apparatus by which the covering yarns are wound automatically and successively.

A rope to be formed into a tubular rug of the present invention comprises side core members 2 and 3 which are made from the same material and are positioned on both sides of a thick central core member 1 made from a suitable material. Desired numbers of first covering yarns 4 which are difierent in color are wrapped helically around the outside of these three core members 1, 2 and 3 and other desired numbers of second covering yarns 5 which are different in color are wrapped only around the outer periphery of central core member 1 in the opposite helical direction to the said first covering yarns 4, and the first and second covering yams 4 and 5. To form a rope a comprised of these three core members 1, 2 and 3 wrapped with the desired numbers of the covering yarns 4 and 5, the covering yarns 5 wrapped around the outer periphery of the central core member 1 are interwoven With the covering yarns 4 which are wrapped around the outer periphery of the three core members 1, 2 and 3, so that a rope having rectangular cross section is provided.

A method of winding the said covering yarns 4 and 5 around these three core members 1, 2 and 3 is carried out continuously and automatically by an apparatus other than the conventional braiding machine as shown in FIG- URE 4.

The three core members 1, 2 and 3 are arranged in a braiding machine which feeds the covering yarns 4 and 5 to bobbins which are driven in the direction of arrows b and c along the eight ringed grooves formed on a circular table. Thus, by movement of a bobbin in the direction of arrow b the covering yarns 4 are wrapped around the outer side of the core members 1, 2 and 3, while by movement of a bobbin in the direction of arrow c the covering yarns 5 are wrapped only around the central core member 1, and bobbin passing between the core members 2 and 1 and between the core members 1 and 3, without wrapping the covering yarn 5 around the outer side of the core materials 2 and 3. Since the paths of the bobbins moving in the direction of arrows b and c are in opposite directions the covering yarns 4 and the covering yarns 5 are interwoven at the positions between the core members 1 and 2 and between the core members 1 and 3.

As mentioned above, for the tubular rug of the present invention, the ropes forming the tubular rug, as shown in FIGURE 2, are made up by interweaving the covering yarns 4 with the covering yarns 5 which interwoven portions appear on the surfaces at the lines between the core members 1, 2 and 3. Thus a rope having a generally rectangular cross section and whose central core member 1 projects convexly is obtained and an oval tubular rug can be formed from this rope or a rectangular ring can be formed by arrangng lengths of this rope in a row.

Moreover, the surface area of a conventional rope formed from three core members becomes wider because the yarns become loose, so there is a danger that the tubular rug will be hurt by scratching with the heel of a high-heel shoe, or will cause a person an injury. However, with the rope of the tubular rug according to the present invention, since the covering yarns 5 are tightened helically in a direction opposite to the covering yarns 4, these covering yarns do not become loose, and accordingly, there is less danger that the heel of a high-heel shoe will be caught in the tubular rug. Also, as the covering yarns 4 and 5 of various colors are used, an unusual pattern which is not obtained with the conventional tubular rug is produced, and a wide and flat rope is formed, so that work efficiency in making the tubular rug can be remarkably improved because fewer ropes are needed compared for a given area of the tubular rug. Hence, a good tubular rug can be provided in an eflicient manner.

What I claim is:

A tubular rug, comprising a rope having a central core member and two side core members, one on each side of said central core member, a plurality of first covering yarns wound in one helical direction around the outside of the three side by side core members, and a plurality direction around only the central core member and'interwoven with the plurality of first covering yarns, said rope being in side by side lengths which together make up the rug.
